Super-family IV FORMICOIDEA. 



These are the ants whose appearance is so commonly known that description 

 seems hardly necessary. The structural character that separates them is the 

 possession of one or two nodes or scales at the base of the abdomen, forming 

 intermediate segments. They are usually social and form colonies, large or 

 small, in which workers or undeveloped females predominate. These are wing- 

 less, but males and females are winged, the female losing these appendages 

 soon after she starts a colony. The larvoe are helpless grubs which must be fed 

 by food properly prepared by the workers. They make their nests in all sorts 

 of places, some of them even inhabiting dwelling-houses, and they are almost 

 omnivorous in feeding habits. None of our species are directly injurious to 

 field crops, but many are indirectly harmful from their habit of protecting 

 plant-lice by storing their eggs and colonizing the insects in spring upon a 

 proper food plant. They may be thus considered injurious on the whole, and 

 they do not in any case feed upon species that are injurious to the agriculturist.
